// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
* Service Description: Service for configuring logs-based metrics.
*
* This class provides the ability to make remote calls to the backing service through method
* calls that map to API methods. Sample code to get started:
*
*
*
* try (MetricsServiceV2Api metricsServiceV2Api = MetricsServiceV2Api.create()) {
* String formattedMetricName = MetricsServiceV2Api.formatMetricName("[PROJECT]", "[METRIC]");
* LogMetric response = metricsServiceV2Api.getLogMetric(formattedMetricName);
* }
*
*
*
* Note: close() needs to be called on the metricsServiceV2Api object to clean up resources such
* as threads. In the example above, try-with-resources is used, which automatically calls
* close().
*
*
The surface of this class includes several types of Java methods for each of the API's methods:
*
*
* - A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available
* as parameters, and not every API method will have a flattened method entry point.
*
- A "request object" method. This type of method only takes one parameter, a request
* object, which must be constructed before the call. Not every API method will have a request
* object method.
*
- A "callable" method. This type of method takes no parameters and returns an immutable
* ApiCallable object, which can be used to initiate calls to the service.
*
*
* See the individual methods for example code.
*
*
Many parameters require resource names to be formatted in a particular way. To assist
* with these names, this class includes a format method for each type of name, and additionally
* a parse method to extract the individual identifiers contained within names that are
* returned.
*
*
This class can be customized by passing in a custom instance of MetricsServiceV2Settings to
* create(). For example:
*
*
*
* MetricsServiceV2Settings metricsServiceV2Settings = MetricsServiceV2Settings.defaultBuilder()
* .provideChannelWith(myCredentials)
* .build();
* MetricsServiceV2Api metricsServiceV2Api = MetricsServiceV2Api.create(metricsServiceV2Settings);
*
*
